In the operation of the device,the cart may be placed either horizontally or vertically and the load such as a afcarcass 90 may be placed on the cart in any denmdmannen If desired, the line 88 may be extended mthe socket 62 and the hook 70 may be attached themes, after which the winch 72 may be operated humflierline 68and cause the carcass to be dragged After the carcass has been placed on of theme piece 46 or by means of the hook 70.

In the event a desired to go up or down a stairway, the angulation Ii] be such that the skids will touch the edge of the treads so that the wheels will be substantially inoperative QM :the'ldevice may be slid up or down the stairway. M it dsldesired to lift the carcass upwardly and hang it on a support, such as one of the hangers 92, the cart is maneuvered into position .and stood upright, after which flw'winchmay be operated to bring the hook member into-the socket 62 and raise the bed 50 upwardly along the frame-1 Obviously, to reverse the proceedings the hook wfll be engaged with the meat 99 and the bed ele- I-lhd further to release the meat from the hooks 92 after, Ihidt it may be lowered into carrying position.

alt will be apparent that the present invention provides a eonvenient means foreither carrying or lifting meat or he! articles without the necessity of manual handling For the purpose of exemplification a particular embodiment ofthe invention has been shown and described according to the best present understanding thereof. However, it will be apparent to those skilled in the art that and modifications may be made in the construction and arrangement of the parts thereof without defining from the true spirit and scope of the invention. 6 What is claimed as new is as follows:

1. A cart comprising a substantially flat longitudinally frame, a pair of skids extending in spaced parrelation to'said frame, angulated front end portions skids securing said skids to the forward portion ot's'aid frame, said front end portions extending rear- I'ardl'yin angular relation to said frame, rear end porfiom securing said skids to said frame at a point'remote to-the forward portion of the frame, wheels mounted on said angulatcd front end portions, a substantially flat bed vtelescopically mounted on said frame, a winch on said frame intermediate the ends thereof, a drone-mounted adjacent the rear end of said frame, a leeeadcheave mounted on the underside of the bed adiaee'nt the front end thereof, a third sheave mounted on the runend of said bed, a flexible tension member se- M onsaid winch and entrained over said sheaves in aeqnenee, a hook socket fixed to said bed in aligned relation with said third sheave, said flexible tension memsaid socket, and a hook secured to the free end of said flexible tension member.

2- 4 lift cart comprising a substantially fiat rectangua pair of skid portions, angulated end members securing the front ends of said'skids to the forward portion of said frame, handle portions securing the rear ends of said skids to said frame, an axle mounted transversely of said angulated end portions, a pair of wheels journaled on said axle, one portion of the periphery of said wheels being tangential to said skids, another portion of the periphery of saidewheels being tangential to the end of said frame, a fiat bed longitudinally slidable on said frame, a winch mounted on said frame, a first sheave mounted adjacent the rear end of said frame, a second sheave mounted adjacent the front end of said bed, a bracket mounted on the rear end of said bed, a hook socket fixed on said bracket, a third sheave mounted in said bracket, a flexible member secured on'said winch and extending throughsaid hook socket, said flexible member being entrained over said sheaves, and a hook secured to the free end of said flexible member.

3. A trundle lift cart comprising an elongated frame having a pair of handles at one end, an axle mounted transversely of the other end-of said frame, a pair of wheels journaled on said axle, a flat bed extending longitudinally of said frame, means supporting said flat bed and guiding the same for longitudinal movement with respect'to said frame, a manually operable winch mounted on said frame adjacent said handles, a flexible tension element operatively. secured to said winch, a first sheave mounted on said flat bed toward said axle and wheels, a second sheave mounted on said flat bed toward the opposite end thereof, said flexible tension element being trained about said first sheave and then said second sheave, article securing means fixed to the free end of said flexible tension element, and arresting means to prevent retraction of said flexible tension element from said second sheave whereby operation of said winch first causes said article securing means to be drawn toward said second sheave until arrested by said arresting means and continued operation of said winch thereafter moves said flat bed longitudinally of said frame.

4. A trundle lift cart comprising an elongated frame having a pair of handles at one end, an axle mounted transversely of the other end of said frame, a pair of wheels journaled on said axle, a flat bed extending longitudinally of said frame, means supporting said flat bed and guiding the same for longitudinal movement with respect to said frame, a manually operable winch mounted on said frame adjacent said handles, a flexible tension element operatively secured to said winch, a first sheave mounted on said flat bed toward said axle and wheels, a second sheave mounted on said flat bed toward the opposite end thereof, said flexible tension element being trained about said first sheave and then said second sheave, article securing means fixed to the free end of said flexible tension element, arresting means to prevent retraction of said flexible tensionelement' from said second sheave whereby operation of said winch first causes said article securing means to be drawn toward said second sheave until arrestedby said arresting means and continued operation of said winch thereafter moves said flat bed longitudinally of said frame, and means to lock said winch.
